Locksy - Tab Locker & Password Protection

Password-protect your tabs with military-grade PBKDF2 encryption and instant biometric unlock (fingerprint / Face ID / Windows Hello). Instant locking, offline security, 100% private.

🎯 WHY YOU NEED LOCKSY?

Do you work in shared spaces or need to step away with sensitive tabs open? Locksy provides enterprise-level tab protection with PBKDF2 key derivation (600,000 iterations) and WebAuthn biometric authentication. Whether it's banking, confidential work documents, or personal messages - Locksy keeps your tabs secure with military-grade password protection and instant biometric unlock.

🔐 LOCKSY vs DEVICE LOCK?

❌ OS/Device Lock DOESN'T PROTECT:
• Screen sharing sessions - Others see your tabs during meetings
• Quick shoulder surfing - Seconds to glance at your screen
• Shared computers - Family members with access see everything
• Individual privacy - Lock ENTIRE device for ONE sensitive tab

✅ LOCKSY PROVIDES INSTANT, SELECTIVE PROTECTION:
• Lock ONLY sensitive tabs, keep working on others
• 1 second vs 5-10 seconds for device lock
• Works DURING screen sharing - Hide specific tabs while presenting
• Tab-level control - Lock banking, keep email accessible
• Auto-lock after inactivity - Set and forget protection
• Scheduled locking - Automatic protection during specific hours
• Biometric unlock - Touch fingerprint reader or use Windows Hello instantly
